Original, pretty and practical

So a "hub Castle", as it is otherwise known only from old vaults, can be seen in this country rarely in use. It is super convenient to open with one hand! The three numbers from 0-39 are not more difficult to remember than eg the four digits "normal" combination locks, offer as this not only 10,000 combinations (= 10x10x10x10) but proud 64,000 (40x40x40).
The housing is not solid, as we know it "usual" of the brass padlocks. Do not know if that also means less security, the inner workings of things not seen, yes.
Overall, however, the castle looks very stable and looks in metallic blue with something darker, matt-blue hub also still very pretty.
I would buy this again at any time.
